本研究以結構式問卷調查法探討國內護理人員經前不適之盛行率、影響因素，及經前不適因應行為。以郵寄自填問卷收集資料，回收問卷662份，有效者598人。研究結果顯示樣本過去曾有經前不遠的盛行率為84.9%'最困擾的經前身心變化依序為:情緒問題、腹部不適、疼痛、荷爾蒙相關症狀等。單變項分析顯示:年齡、婚姻狀況、工作年資、及過去三個月內月經來潮時疼痛程度與經前不適有顯著相關。兩組對數複迴歸顯示年紀愈輕者，過去曾出現經前不適可能性愈高;月經來潮時疼痛程度愈嚴重者，過去曾有經前不適的可能性愈高 ; 過去曾有經前不適者，則其月經來潮時之疼痛程度為決定其經前不適程度之因子;而來潮期疼痛程度愈高，其經前不適的症狀亦愈嚴重。
